Salivary Gland FNA: Anatomic, Clinical, and Technical Considerations

چکیده

The major salivary glands consist of the parotid, the submandibular, and the sublingual glands. Under the control of the parasympathetic nervous system, the major salivary glands are responsible for the principal portion of saliva produced, which can be as much as 1.5 liters per day. The minor salivary glands of the oral cavity, pharynx, and upper airways contribute only a small percentage of the overall volume of saliva, but they are particularly important for supplying the mucus layer that protects the tissues of the oral cavity and upper respiratory tract. Embryologically, the major salivary glands develop during the 6th to 8th weeks of gestation. The parotid gland arises first from ingrowth of the oral ectoderm into the surrounding mesenchyme. By the 7th week of development, the parotid gland moves in a dorsal and lateral direction to reside in the preauricular region, and by the 10th week, the facial nerve divides the surrounding parotid gland into anatomic superficial and deep compartments. A majority of parotid gland tumors develop within the superficial lobe, making FNA and clinical management relatively easy. Tumors originating within the deep lobe of the parotid gland usually present as pharyngeal swellings due to expansion into the parapharyngeal space. The parotid gland is unique among the salivary glands in that it incorporates lymphoid tissue during development, sometimes with entrapment of salivary gland epithelial cells. The latter are believed to be the source of lesions such as Warthin tumor and lymphoepithelial cysts. The minor

Clinical usefulness of fine needle aspiration cytology in patients less than 20 years old: a 10-year experience at a single institution.

The purpose of this study was to identify the spectrum of cytological diagnoses and evaluate the diagnostic effectiveness of fine needle aspiration cytology (FNA) in patients less than 20 years old. The subjects were selected by retrospectively reviewing records from 1999 to 2009. Selected patients less than 20 years old underwent FNA. Cytological and histological slides of samples from the sub...

Fine-needle aspiration cytology of lymphoproliferative lesions involving the major salivary glands.

Fine-needle aspiration biopsy (FNA) is an accurate and cost-effective procedure for evaluating salivary gland lesions. Lymphoproliferative lesions may manifest as salivary gland enlargement. We report our experience with 43 cases of reactive and neoplastic lymphoproliferative lesions of the salivary glands evaluated by FNA, including 23 cases of reactive lymphoid hyperplasia and 20 neoplastic l...
